Netmask Changes in Solaris 10

Hi Team,
We tried to change the netmask and broadcast address in solaris 10 by below steps
ifconfig ipge0 down
ifconfig ipge0 <ipaddress> netmask <subnet mask> broadcast <address
ifconfig ipge0 up
But interface is not up. The command (ifconfig ipge0 up) is hanged for long time without giving any error.
So, we changed the new netmask in the /etc/inet/netmasks and rebooted the server. The new changes got affect only after reboot.
Could you please confirm the Solaris 10 requres reboot for changes in netmask.
Regards,
R. Rajesh Kannan.

No, it doesn't need a reboot.
In fact, you don't even have to take the interface down....
I would edit /etc/netmasks so that the correct setting was in there for the next time I booted. Then:
'ifconfig <interface> netmask + broadcast +' (Yes, with the '+' symbols).
That should do it. No need to down or up.

Changes in Solaris 10 Patch Access Policy

Solaris 10 x86 User Community
As of November 29th, Sun will be changing its Solaris 10 patch access policy. Now that Solaris 10 is freely available, support services require the purchase of a Sun Service Plan.
Under this new policy, access to patches is restricted. Security fixes and hardware driver updates are publicly available for free, but access to all other patches requires a Sun Service Plan.
Please see http://www.sun.com/service/sunconnection/solaris10patches.html for available access options.
Please send any questions to [email protected]

hi,
As a technical specialist I can understand everyone needs revenues to keep on going. But $120 for a min. level service plan it's really foolish on the policy makers. This would result in severe dent for the Solaris initiative itself in the long run. There should be reasonable pricing model, especially when Sun is projecting Solaris as an alternative to Linux! I do strongly suggest as a loyal Sun developer since 1996 to re-consider the service plan rates.
thanks,

Networking changes between Solaris 10 x86 10/08 (u6) and previous versions?

Solaris Community:
We have a J2SE CORBA-based application (that uses the default Sun ORB) that has run without problems on Solaris 8, 9, and 10 on both SPARC and, more recently, X86 platforms. Upgrading our client side machine (X4100 M2 Opteron platform) from Solaris 10 x86 5/08 (u5) to Solaris 10 x86 10/08 (u6) has resulted in threading or socket contention issues that we have not experienced previously. Using Live Upgrade, we can quickly go back to the u5 install on the client machine .... and the problems go away .... going back to u6, however, and the problems begin to show almost immediately. Our Java code base is identical as is the version of the JDK (1.5.0_16), so it would appear that there must be an underlying change to socket, networking, or threading behavior between these two versions of Solaris.
Thus far, I've not been unable to find details of changes either in the networking support or the threading model that might explain this .... or course, I don't have great expertise in these areas.
I've tried to use 'ndd /dev/tcp SOME_PARAMETER' for all of the /dev/tcp parameters returned by 'ndd /dev/tcp \?' to try to see if there are underlying changes in the /dev/tcp parameters .... but have not found any differences between Solaris 10 u5 and u6.
Can anyone point me to resources that would discuss changes between Solaris 10 u5 or u6 that might explain the problems that we've encountered? Or, alternatively, other system parameters that I could check that might explain changes in either TCP socket or threading behavior?
Thanks for your input,
John

I have a vague memory of someone reporting something similar which turned out to be due to a solaris feature called tcp_fusion.
To check whether thats your problem or not try the following.
Add following line in the /etc/system file.
set ip:do_tcp_fusion = 0
Once the /etc/system file is updated, it will be necessary to restart the system before the workaround will take effect.

IP address change in Solaris 10

Hello Friends
while installing solaris I gave some ip address to computer say 192.168.100.x .. , now after installation I have been asked to change the Ip address to some other series say 172.168.100.x , and this IP address should reflect even if reboots the computer. - i used "ifconfig" to change ip but when i m restarting the system its showing the prevoius one ( 192.168.100.x)
what do i do to solve the thing.
regards
Kinshuk

ifconfig only changes the running config.
When you reboot it will be lost.
The easy way is to run sys-unconfig.
Then reboot and it will ask for IP address etc again.
If you know what you are doing, you can edit the files.
Look in the sys-unconfig man page for the list of files it modifies.
The files in question are roughly
/etc/hosts
/etc/inet/ipnodes
/etc/defaultrouter
/etc/netmasks.
if you are changing the hostname as well as the IP then there are more files to change.

Can Host ID be changed on Solaris 10

Recently upgraded an Ultra 10 from Solaris 2.6 to Solaris 10.
Problem:
We use an application that is no longer supported by the manufacturer. The application ran on the Ultra when it had Solaris 2.6. It required a specific host ID because it was originally licensed on a much older system. We cannot get a new license authorization for the application because the company is no longer in business.
To get around this, we used a program called "hid2" to change the host ID of the system. This temporarily changed the host ID on the Ultra and allowed the application to run.
After installing Solaris 10, I run the command "hid2 newhostid", and I get an error "cannot read namelist out of /dev/ksyms". The command to change the host ID is "hid2 newhostid" where newhostid is the ID required by the application.
Is this something with Solaris 10? It worked with the same hardware when the OS was Solaris 2.6.
I need an excutable program like hid2 because I'm not knowledgeable enough to compile C programs. There are several available on other websites but those that are excutabiles didn't work..
Does anyone know what to do? Do I need to install an older version of the OS? I've used 10 a little on a x86 system and like it. I'd like to upgrade this Ultra to 10.
Thank you.

Jonathan,
Keep in mind that the hints given in that Squirrel.Com link work for OBP 3.x systems, only.
When the time comes that you migrate to the next, newer system, it'll likely have an OBP design of 4.x or 5.x or 6.x, and the procedure will NOT work. The mkpl functions were deliberately removed by Sun.
So... it may now be the time to start a budget line item to save up to replace that software. Perhaps find a program that can take advantage of 21st Century computing, with 64bit and CMT architecture. <img src="images/smiley_icons/icon_smile.gif" border=0 alt="Smile">

Zfs kstats changed in Solaris 11 - breaks arcstat

I maintain the arcstat tool here:
[https://github.com/mharsch/arcstat]
I've identified some changes in zfs kstats that have broken this tool for Solaris 11 users. My analysis of the issue is here:
[https://github.com/mharsch/arcstat/issues/4]
Would someone from the ZFS team be willing to work with me to reconcile the kstat changes so users of the arcstat tool can get running on Solaris 11?
The easiest engagement would be in the form of a github pull request, but I'll take anything I can get.

Unable to detect iSCSI LUN size change on Solaris 10

I resized (grew) an OpenFiler iSCSI LUN, but I cannot get Solaris 10 to pick up the change. Using the type -> autoconfigure in format and relabeling the disk ought to do the trick but it does not work. Does anybody know how to overcome this?

Hmm, what filesystem do you have on the disk?
.7/M.

Nslookup output changes between Solaris 8 and 10

I have a customer that has asked why and if the output can be changed to match?
We have noticed a difference on the nslookup reverse lookup with
Solaris 10.
On Solaris 8 we get:
# nslookup x.x.x.x
Server: dnsserver.csd.disa.mil
Address: x.x.x.x
Name: hostname.my.af.mil
Address: x.x.x.x
On Solaris 10 we get:
# nslookup x.x.x.x
Server: x.x.x.x
Address: x.x.x.x#53
x.x.x.x(server ip in reverse).in-addr.arpa name =
hostname.my.af.mil.
Why is the output on Solaris 10 different when doing an nslookup on
the IP
address? The guys who work on the application noticed it and
opened a
ticket. Is there something I can do to get the output to come out
like it
does on Solaris 8.Any and all help would be appreciated....

SPARC doesn't need a split boot loader like BIOS/x86. The OBP can directly load from any slice. So 'boot disk:a' would boot from slice 0 and 'boot disk:g' would boot from slice 6.

NetMask change at VSA environment

Hello all,
I'm planning to change netmask on my VSA environment, since i ll only change netmask, and I won't make any change on IP address, the change should work transparent as I research, to make this i m planning to make the changes at maintenance mode and then restart the hosts after.
Should I take care about anything else?
By the way, does anyone knows where can I download a trial for vSphere Storage Appliance? is that possible ? I m unable of that at the momento.
Thanks and regards!

Hello,
As per best practices, any configuration change should go through transport process and all master data changes should be done directly in production.
Some examples of changes that can be done directly are.
1. Exchange rates
2. Sets used in validation/substitution (GS01/GS02)
3. All condition records
4. Customer/vendor/GL/Asset/cost center/cost element master data
5. Tax percentages
There are many more follows... Tell us your exact requirement. Then we can guide you better.

How to change current Solaris version for a program?

Hello,
A program I am trying to run under Solaris 5.10 checks the OS version to be 5.8 or 5.9.
Can I somehow tell Solaris to report 5.9 to the program instead of 5.10?
According to "Solaris Application Guarantee" I should be able to run 5.8/9 programs under Solaris 10 with no problems.
Thakns,
Victor

You can use dtrace to manipulate the OS version on-the-fly.
eg.,
% cat sysrelease.d
#!/usr/sbin/dtrace -Cws
#include <sys/utsname.h>
syscall::uname:entry
this->in = (struct utsname *)arg0;
syscall::uname:return
copyoutstr($$1, (uintptr_t)&this->in->release[0], SYS_NMLN);
}This script accepts an argument, the version of our choice; so as long as the script is running, OS returns our input as output to uname -r. Once the script exits, OS returns the true version.
% uname -a
SunOS sunfire4 5.10.1 snv_10 sun4u sparc SUNW,Sun-Fire-1280R
% ./sysrelease.d 5.9
dtrace: script './sysrelease.d' matched 2 probes
dtrace: allowing destructive actions
.. script waits here doing nothing ..
In another window:
% uname -a
SunOS sunfire4 5.9 snv_10 sun4u sparc SUNW,Sun-Fire-1280RComplete the software installation. Once it is done, go back to the previous window, and stop the script by pressing Ctrl-C

Solaris 2.6 - 8 API changes document ?

Is there a document which lists all the library/system call
changes between Solaris 2.6 and 8 (or 2.6->7 and 7->8 docs) ?
I assume that most changes will be new functionality, with
a few obsolete odds and ends dropped ...
I've had a good look around docs.sun.com but have not found
anything which lists the differences.
Thanks,
Bernard

You might get a quicker reply to this if you would
post to the Solaris Forum. People who know more
about the Compiler Collection will waste your time
looking for a doc that Solaris specialists will have
at their fingertips.

Changing casuser password on solaris

Dear *,
I have intalled LMS 3.2 or solaris 10. The installation is successfull. Now i want to change the password of casuser but i am unable to find the resetCasuser. Seems like file is missing. Any idea why? NMSROOT\setup\support\resetCasuser
Is there anyway i can get this file from somewhere and copy it in solaris? Since this is a solaris account what willl happen if i change the password from solaris itself?
Thanks,
Aamir

Hi Aamir:
There is no facility or program to change the password of casuser because one cannot log into the box as casuser; that account has no shell.
grep casuser /etc/passwd
casuser:x:101:100:CiscoUser:/opt/CSCOpx:/dev/null
Even if you change the Solaris user password, that account still can't be logged into.

Change IP online permanently

I looking for the right way to change IP permanently without using sys-config.
The OS level is Solaris 9.
This is the sollution I am planning:
1.
ifconfig -a (to view)
ifconfig hme0 down
ifconfig hme0 unplumb
ifconfig hme0 plumb
ifconfig -a (to view)
ifconfig hme0 inet uuu.xxx.yyy.zzz upIt is another network so I will change 3 files
vi /etc/hosts (change ip)
vi /etc/netmasks (change netmask)
vi /etc/defaultrouter (change route)the file /etc/hostname is correct.
Will this work...
/etc/init.d/inetsvc stop
/etc/init.d/inetsvc start
ifconfig -a (view IP)
netstat -rn (view route)
ping uuu.xxx.yyy.zzzIs there better commands?
Should I do it in another order?
BR,
Jaton

None of the commands are necessary. Feel free to view, but you don't have to down or unplumb anything.
>
ifconfig hme0 inet uuu.xxx.yyy.zzz upRecommend that if the new address is in a different subnet you verify /etc/netmasks is correct for it. Then I would:
ifconfig hme0 uuu.xxx.yyy.zzz netmask + broadcast +
It is another network so I will change 3 files
vi /etc/hosts (change ip)
vi /etc/netmasks (change netmask)
vi /etc/defaultrouter (change route)
Change netmasks immediately. If you're changing subnets, you'll need to change your routes.
route delete net default <oldgw>
route add net default `cat /etc/defaultrouter`
the file /etc/hostname is correct.
Will this work...
/etc/init.d/inetsvc stop
/etc/init.d/inetsvc start
No. inetsvc doesn't take arguments. There's no such thing as "stop".

Step by Step Guide to Install Solaris 10 11/06 With Windows XP on x86 PC

hi everyone
here is how I fixed my dual boot & internet connectivity failure problems. I'm explaining in detail to help any Solaris newbie (like me) having same problems: ( as I didn't find any REAL Help thru Sun Help Documents / Pages )
My special thanx to " Phil Brown " ( who helped me alott on this )
First to get rid of Dell's Diagnostic Partition & System Recovery Partition I re-installed Windows XP Media Center Edition & at installation I made 4 Partitions of my Dell 9150 ( x86 Intel Pentium Dual Core ) 238 GB Hard Drive.
(1) C: 100 GB for Windows XP ( NTFS )
(2) D: 80 GB for Solaris 10 ( RAW )
(3) E: 50 GB for Linux ( RAW , which I haven't installed yet )
(4) F: 6 GB (RAW)
(5) G: 2 GB Un-Allocated Space
Restarted PC after Win XP installation & installed Partition Magic 8 . In PM8 I formatted Solaris partition as FAT 32 (at Solaris installation it changed to Solaris format) & Linux as Linux EXT 3 . Rebooted the PC. I Started Solaris 10 11/06 installation from the DVD I burned from Sun downloads.
Here's how I installed Solaris 10 11/06 :
(1) On the next screen after "Loading Stage 2 ... " I selected " Solaris "
(2) Selected " Solaris Interactive (default) installation
(3) Hit "enter" to accept proposed Windows configuration screen it displayed
(4) Selected 0 = English as language (you need to take cursor into white window so you can type 0 into it, otherwise u can't)
(5) hit NEXT
(6) Selected "Networked" option
(7) Selected YES to "Use DHCP for e1000g0 ( Intel Pro/1000 Network Adapter )
(8) Selected NO to "enable IPv6"
(9) Selected NO to "enable Kerberos"
(10) Selected DNS as "Name Service"
(11) entered " f.root-servers.net " as Domain Name
(12) Server's IP address : 192.5.5.241 ( you can choose the one that closest to you by visiting http://www.isc.org/index.pl?/ops/f-root/ )
(13) Search Domain: Left all boxes empty ('coz when I tried to put any IP's into 'em, it generated " SysidgenSyserr " and have to re-start installation )
(14) Geographic Continent / Country / Region: Americas > U. S. > time zone
(15) hit NEXT on Date & Time Screen
(16) Entered password twice
(17) Selected YES to "enable Remote Services"
(18) hit CONFIRM
(19) Clicked NEXT on Solaris installation Welcome screen
(20) Selected NO to " Reboot Automatically " and YES to eject additional CD/DVDs
(21) Clicked OK on NOTICE
(22) Specified CD/DVD as " Media from which you installing Solaris "
(23) Check ACCEPT & hit next
(24) Selected "initial install" & hit next
(25) I choose "Custom Install" > NEXT > North America > and checked both, " English ( U S ) ( en_us) & English ( U S, UTF-8) (en_us.UTF-8) and hit next
(26) Selected English (US, UTF-8) as initial locale > NEXT
(27) Selected " Solaris 10 Extra Value Software " > NEXT
(28) Selected NONE to " Web Start Ready Product Scan Location " > NEXT
(29) Selected " Entire Group - Default Packages " in Solaris software group screen > NEXT
(30) Selected " c1do(bootdisk) " > NEXT
(31) " c1d0 " Selected > NEXT
(32) There was a Warning: " A Linux fdisk partition was found on this disk (c1d0), which is the default bootdisk. Having a linux fdisk partition on the same disk as a Solaris fdisk partiton is not supported. Do you want to load the default Lay out ? I choose NO
(33) It displayed 4 partitions. 1st: " Unknown " 100GB , 2nd: FAT32LBA, this I changed to Solaris by clicking on partition, size 80GB . 3rd: Linux 50GB , 4th: DOSEXTLBA 8GB , hit NEXT
(34) I choose NO to " Preserve Data Warning " (the 80GB partition)
(35) Displayed " Lay Out File Systems " screen, c1d0 was highlighted. > NEXT
(36) On " Ready to Install Screen " it displayed Fdisk partitions: 1st: Unknown "Preserved" , 2nd: FAT32LBA delete, & Solaris add, 3rd: Linux "Preserved" , 4th: DOSEXTLBA "Preserved" >>> hit " Install Now "
(37) When installation finishes hit " Reboot " & when PC was restarting I ejected DVD manually
(38) After re-start it displayed 3 options: 1st: Solaris 10 , 2nd: Solaris failsafe , 3rd: Windows , ENTER on Solaris 10
(39) At sign-in screen, I signed in as, user name: " root " & enterd password (which I typed at installation)
(40) I choose JAVA Desktop System
When it was fully up, the Internet was working right away. Restarted again to check Windows. Selected " Windows " at reboot screen & Windows was working just fine.
It took me few allnighters to figure these out, I hope these will helpful to Solaris newbies like me. Still I can't figure out ... How to install any software (obviously designed for Solaris 10 (x86) ) onto Solaris, but thats a different issue.
- Jags Desai

"A Linux fdisk partition was found on this disk (c1d0), which is the default bootdisk. Having a Linux fdisk partition is not supported"
It might not be supported, but it works fine for me on my thinkpad :-) .
redhat/solaris/xp.
You can't just use the linux grub, though, because it won't understand
solaris 'slices within partitions'. You need to get Solaris to install
grub itself (in fact, you can't stop it doing so, which is rather unfair),
and then add in the linux * xp entries to Solaris's /boot/grub/menu.lst
(== grub.conf) to get it to pick up fedora & xp. Chainloading xp worked
fine for me. Chainloading RHEL4/5 doesn't, so I had to cat the grub.conf
from red hat on to the end of solaris's menu.lst. Stick red hat's grub.conf
on a USB pen or just write it down before putting Solaris on, otherwise you'll
have to boot linux rescue of a red hat CD in order to get hold of it after
Solaris's grub takes over.

Solaris in Logical Partition and Internet Configuration

Hi !
I'm really passionate about this unix-solaris thing.
But these nudges are pulling me back from installing it actually in my hard drive.
And also there is the Internet configuration problem.
Problem:1
I have 2 IDE HDD.
Primary HDD: 80 GB
VolumeName-Type-Size
SystemBoot-Primary/Active/NTFS-100 MB
Extended Partition:
VISTA-Logical/NTFS-20 GB
2008-Logical/NTFS-10 GB
Data-Logical/NTFS-25 GB
Music-Logical/NTFS-9.42 GB
Solaris-Logical/BLANK-10GB .....Blank = No FS. Used Acronis DD10 for it.
Slave HDD: 40 GB
Extended Partition:
XP-Logical/NTFS-10GB
Fedora9-Logical/ext3-10GB
SWAP-Logical/SWAP-2GB
OpenSUSE103-Logical/ext3-15.25 GB
When I came to HDD configuration stage of installation,
I selected the pre-selected c0d0(bootdisk) ---Primary HDD/80GB.
But when I proceeded further it showed me:
Warning � The initial fdisk information found on the disk
c0d0 was invalid. Defaulting the entire disk to a Solaris partition.
So I aborted the installation.
I tried one more time, by changing the Solaris Blank logical drive to a primary partition.
But it didn't work.
Now I think Solaris 10 cannot be installed in a logical drive or more broadly speaking(assuming) it cannot be installed in HDD having logical drives,it should be all primary partitions.
Please help me on this.
I'm sick of installing it in VMWare.
Problem: 2
How am I supposed to configure my network connection.
I connect to my ISP using WAN Miniport(PPPOE).
It allots me dynamic IP(v4).
I read somewhere DNS should f.root-servers.net and in a magazine, a.solaris.net
I never came across such a thing in even in linux.
Problem: 3
If there is not so �feasible� solution to problem 1, VMWare Workstation comes into play.
And here too, I need help for configuration of network connection.
These are the values that I got when I installed Windows XP in the VMWare.
